How to do a good job of technical control of the gloss quality of facial paper?

The varnish layer of the pre-printed carton surface paper is over-bottomed and the film surface is damaged, which is the main reason for the unqualified quality of the surface paper.

Among them, the way the semi-finished products are placed in the air and the stacking volume are not suitable are the main reasons for the adhesion of the upper and lower sheets to cause the bottom. Especially when the top paper is full of green and blue printing layouts, it is easier to make the top and bottom papers. There are adhesions between each other and the bottom of the coating will damage the glazing film surface.

　　 Therefore, it is best to use a drying rack equipped with a blowing device to put the paper in an upright position as far as possible for the glossy green and blue printed surface paper. If there is no special drying rack for drying, the glazing surface paper should be stacked on a flat surface. The height of each stack should be controlled at about 25cm. After the coating layer is dry, the semi-finished products should be stacked and stacked. However, the stack height of dry semi-finished tissue paper should not exceed 150cm.

　　 In addition, pay attention to adjust the appropriate ratio of the glazing paint to the thinner. The concentration of the glazing paint should not be too high. A relatively suitable mixing ratio should be mastered according to the characteristics of the surface of the glazing paper. When changing glazing paints of different manufacturers and models, you must first prepare a sample for test glazing, carefully observe and analyze the test glazing process, and then formulate a more appropriate mixing ratio to avoid blindness The glazing paint is deployed to make the facial paper adhere to each other and destroy the film surface, which can better ensure the qualified quality of the facial paper glazing.
